16 Claims.

This invention relates to air conditioning appa ratus, and has for its object to provide means to receive air from a room, condition it and discharge it back into the same or similar rooms.

It is the object of this invention to provide means fortaking air from a room by means-of pipes located adjacent the floor, condition the air by removing therefrom dust, germs and other foreign matter, heating or cooling the air and discharging the air thus conditioned back into rooms by means of discharge pipes located beneath the floors of the rooms.

It is also an object 'of this invention to provide means for forcibly withdrawing air from a room,

matter therefrom, heating or cooling the air and conducting it back into a room. In case the air is cooled, means is provided for catching the accumulated moisture, due to sweating, and conveying the moisture collected away so that it is out of the path of the current of air being conditioned.

It. is also an object of this invention to provide u an air conditioning apparatus in which there is This means is located and supported independent of the air conditioning and air treating means so that no vibration of the motor is transmitted to any part of the conditioning means.

It is a further object of this invention to provide, in connection with air conditioning means, a plurality of long, fibrous stockings in which the air is drawn and through which it passes for removing therefromdust and solid particles, and otherwise treating the air.

These and other advantages will appear from the following description taken in connection with the drawings, in which there is shown a preferred embodiment of the'invention.

A Referring to the drawings:

treating it for removing dust and other foreignmeans for compelling or forcing a current of air.

Figure 5 is a vertical section on the line 5-5 Figure 6 is adetail view showing the manner in which the comers of the casing are formed.

' In Figure lthere is shown a top plan view of easing 1, which has connected to one side a pair of inlets 2. It'also has connected to the other 30 side a plurality of outlets 3. This casing, and the inletand outlet pipes, as shown in Figure 1, are located beneath the floor of a room or building in which the air is treated, and all inlets and outlets are connected to the top of the casing. The casing is composed of sheet metal and has the usual top, as shown in Figure 1. To this top are attached sides and a front and a back.

For supporting the back there is provided around the back part of the casing backangle irons 4. These angle irons extend across the top, down the sides and across the bottom. 'Extending transversely and vertically between the back angle irons are T-irons 5. These T-irons' and back angle irons form the back of the casing N into panel structures in which there are back panels 6 and back panel doors '7. The doors are. used for the purpose of inspection and reaching into the casing for any purpose, such as removing from and placing in the casing stockings'or other parts of the apparatus.

In the front there are angle ironsil, similar to the back angle irons 4.. There are also provided in the front T-irons 9. These T-irons divide the front into panels 10. The sides of the 5 casing also have side angle irons 11 and T-irons 12. The sides are divided by the angle irons and the T-irons into panels 13 and side panel doors 14. .The casing is substantially rectangular in shape and is mounted upon the concrete floor of W a basement or some other suitable supporting means.

Extending transversely from side to side and nearer the back than the front is a partition 15. This partition extends downwardly from the top of the casing substantially half-way to the bottom of the casing. The partition 15 divides the easing into an inlet chamber and an outlet chamber. One chamber 16 is the air inlet chamber; the other chamber 1'7 is the air outlet or the heating chamber. It is in this chamber that the heating apparatus is located and from which the outlets extend. The partition 15 passes into and forms a substantially rectangular air duct 18. The

form of this air duct is shown in Figure 2, as

neath the angle irons 19. There are two of these angle irons, one in front and the other directly beneath the partition 15. The inlet chamber is provided with a floor 20, which has a plurality of holes 21 therein. Around the edge of each hole there is formed a ledge or seat 22. Into each hole there is fitted a filter stocking 23, which has on its upper end a bead 24 for resting upon the ledge. This. bead is formed in the upper end of the stocking by means of a wire or a coil spring around which the open end of each stocking is coiled.

These stockings are relatively long and extend all the way from the floor of the inlet chamber to the bottom of the casing. These stockings are made of some suitable fabric, and are adapted to catch and retain dust and other foreign matter that may be in the air coming through the air inlet chamber. The fabric of these stockings may also be treated so that disease germs and other similar deleterious organisms may be removed or destroyed. The air passes through the walls of the stocking by means of suction created by a fan located beneath the heating chamber, and in order to cause the free distribution of the air to the fan there is provided a bailie' plate 25. This bafiie plate may be made in any suitable form or size, and has holes therein through which the air may pass.

By means of long stockings the stockings may be used for a considerable length of time before removing and cleaning. Dirt, etc. that accumulates in the stocking will drop to the bottom, and since the stockings are long, each stocking may be used for a long time before cleaning is necessary. When it is desired to clean the stockings they may be removed through the back panel door '7 and the same stocking may be replaced or an other one put in its place.

Located below the heating chamber and adjacent the floor supporting the casing is a fan shaft 26 supported on supports or pillars 2'7. 0n the end of the shaft outside of the casing 29 there is a pulley 28 for rotating the shaft and fan. The casing is provided with inlets 30 for taking in the air after it has passed through the filter stockings.

The casing is also provided with outlets 31. There are two of these casings, as clearly indicated by Figure 3. The lower end of the air duct is divided into two parts by an A-shaped partition 32. This partition, with the walls of the air duct, provide two air inlets 33 into which the air duct 18 opens. These inlets are located immediately above the outlets 31 and each inlet is connected to an outlet by means of a pliable connection 34 formed of some suitable fabric, rubber or any suitable pliable material.

In each section of the fan casing there is a fan 35, rotated by the shaft 26. By means of these fans the air is drawn in through the inlets, down through the stockings, in through the inlets 30, through the out lets 31, through the inlets 33, and into the heating chamber where the air is either heated or cooled, owing to the condition of the radiators 37. The fan casing is volute in shape, with its inlets at the sides and its outlets at the top. Each fan casing is supported by means of legs 36 directly upon the floor of the basement or room in which the conditioning apparatus is located.

From an examination of Figures 2 and 3 it will appear that the fan and fan casing are supported independently of any other parts of the conditioning structure. There is absolutely no connection whatever between the fan and the fan shaft and any other structure. Ther is no connection between the fan casing and any other structure except by means of the pliable connections 34,. and these connections are for the purpose of preventing vibration being transmitted from the fan casing to the air duct orv any other part of the conditioning apparatus.

The air tempering, heating or cooling means are the radiators 37, suitably located upon and supported by the angle irons, 19 at the upper end of the air duct 18. To the radiators there is an inlet 38 and an outlet39. For the purpose of heating the radiators steam or hot water may be used. For the purpose of cooling the radiators cold water or any other suitable liquid or gas may be used. The point at which the heating or cooling element enters the radiators is the point where there is a maximum difference between the temperature of the air and the temperature of the conditioning elements. In other words, the air to be heated comes in contact with the hottest part of the radiators. The air to be cooled comes in contact first with the coldest part of the radiators.

In order that the air passing from the fan up through the air duct 18 may be equally distributed to all parls of the radiators, distributor plates 40 are provided. These plates extend lengthwise across the casing from side to side, and each has .105 at its lower edge a triangular trough 41. These distributor plates first extend vertically downwardly, then are bent, in the present instance,

toward the front of the casing so that no air can pass through the distributor plates in a straight line, and also so that no drippings from the radiators canpass by the distributor plates without being caught in the troughs 41.

When the air is being heated'these plates serve to distribute the air alone. When the air is being cooled and more or less warm air is passing over the cooling radiators, condensate is formed on the radiaiors so that drippage will take place, and it is the purpose of these troughs to keep any drippings that may fall from the radiators 190 and prevent the drippings from getting into the fans or other, parts of the apparatus. These troughs incline from one side to the other of the casing and conduct the condensate therefrom to a trough 42 which extends from the rear of the air duct 18 to the front, and discharges the condensate caught therein into a drain pipe 43. This drain pipe conducts the water condensed to any suitable point.

In Figure 6 there is shown a plan or scheme by 13g which the various angle irons can be attached to each other at the corners, and also the manner in which the parts 13 and 6 are attached to the angle irons is shown. The angle irons 4 and 11 are attached to each other by means of a bolt 44. To the angle irons 4 and 11 the panels 6 and 13 are attached. This figure illustrates the manner in which the angle irons are attached to each other at each corner of the casing, and also illustrates the manner in which the panels are attached to the angle irons.
